Uses a LOGO program and probability to solve systems of equations. Provides a physical model and a LOGO model. Lists programs and explains the methodology used. (MVL)

Includes a list of favorably reviewed science and mathematics microcomputer software for instructional use in preschool through grade 12. Developed as an aid to educators in locating programs they may want to preview. (MVL)

Provides a software program for determining PI to the 15th place after the decimal. Explores the history of determining the value of PI from Archimedes to present computer methods. Investigates Wallis's, Liebniz's, and Buffon's methods. Written for Tandy GW-BASIC (IBM compatible) with 384K. Suggestions for Apple II's are given. (MVL)

Classroom interactions of seventh-grade girls and boys who differed in confidence in their ability to learn mathematics were compared. Boys were involved in more public interactions with their teacher than girls. High-and low-confidence students differed very little in their interactions with the teacher. (Author/DC)

Discusses Alabama's attempt to provide computer aided instruction in remedial and initial instruction. Describes the program's funding, obstacles, and mileposts. Lists five phases for program development of competency software. Notes that 125 mathematics and five reading programs are available. (MVL)

Describes two activities to introduce or extend the concept of the natural number e. Students conduct a lottery using either a table of random numbers or a computer simulation to link experimental probability results to the theoretical probability and to the number e. (MDH)

Methods use to reconstruct traffic accidents provide settings for real life applications for students in precalculus, mathematical analysis, or trigonometry. Described is the investigation of an accident in conjunction with the local Highway Patrol Academy integrating physics, vector, and trigonometry. Class findings were compared with those of…

Presents the results of a preliminary investigation into the feasibility of teachers constructing their own animations for the mathematics classroom using computer animation tools. Provides examples of animation constructed using "Ani ST" and "Mathematica" programs. Concludes that computer animation has potential to be a…

Describes the team selection process and the organization of the mathematics component of the Environmental Studies Academic Pentathlon. The mathematics component consisted of environmental research, research methodology, and statistics. Groups submitted papers on seven environmental issues, and individuals designed and reported research studies…

Described are activities that use a hundred chart to improve student abilities to recognize and describe number patterns, to use variables, to make and informally prove conjectures, and to communicate mathematical ideas to classmates. Included are the directions, four reproducible student sheets, the answers, and extensions. (KR)

Discussed is how the concept of equivalence can relate various segments of a mathematics program and help students develop an appreciation of the unity of mathematics. Activities and examples of equivalence at all grade levels are included. (KR)

Suggests 10 no-cost, or low-cost, criteria to be considered by school administrators and curriculum coordinators when educational technology plans, involving the use of calculators, computers, television, video, and research equipment, are in the developmental stage. (JJK)

Describes and illustrates the Monomial Sums Approach, a graphical learning strategy, facilitated by microcomputer capabilities that allow easy manipulation and exploration of graphical representations of polynomial functions. Reduces emphasis on memorized rules in favor of qualitative understanding of functional behavior, visualization of…

A recent structural model suggesting that nine factors exerted effects on seventh grade students' mathematics achievement and attitude was further tested with a national sample of 2,500 tenth grade mathematics students. The structural model, evolved and cross-validated with the younger sample, significantly accounted for variance in mathematics…

Describes a partnership that was formed to develop a fiber optic interactive network and its interface with the development of algebra curriculum and social services in the PATH (Partnership for Access to Higher) Mathematics project in Texas. Equipment connections, costs, and classroom layout are described; and social work components are…
